New genera and species of Jumping Ground Bugs (Hemiptera: Schizopteridae) in Dominican and Burmese amber, with a description of a meloid (Coleoptera: Meloidae) triungulin on a Burmese specimen

Summary

New genera and species of jumping ground bugs (Hemiptera: Schizopteridae) are described in Dominican and Burmese amber. In Dominican amber are described: Hypselosoma dominicana Poinar & Brown sp. n., Schizoptera dominicana Poinar sp. n. and Schizoptera hispaniolae Poinar sp. n. In Burmese amber are described: Lumatibialis burmitis Poinar gen. et sp. n. and Hexaphlebia burmanica Poinar gen. et sp. n. A triungulin attached to the dorsum of the abdomen of Lumatibialis burmitis is described as Microentomus epibatus Poinar gen. et sp. n. in the family Meloidae (Coleoptera). This specimen represents the oldest known triungulin and the first fossil phoretic association of a triungulin and hemipteran.

Résumé

De l’ambre de l Dominique, on décrit Hypselosoma dominicana Poinar & Brown sp. n., Schizoptera dominicana Poinar sp. n. et Schizoptera hispaniolae Poinar sp. n. De l’ambre de Birmanie on décrit Lumatibialis burmitis Poinar gen. et sp. n. et Hexaphlebia burmanica Poinar gen. et sp. n. Un triongulin attaché au dos de l’abdomen de Lumatibialis burmitis est décrit comme Microentomus epibatus Poinar gen. n. et sp. n., de la famille des Meloidae (Coleoptera). Ce spécimen représente le plus vieux triongulin connu et la première association phorétique fossile d’un triongulin et d’un hémiptère.
